SPECIFICATION forming part of Letters Patent No. 291,766, dated January8, 1884.

Application filed May 3l, 1863. (No model.)

To all whom it may concern.:

Be it known that I, CHRISTIAN LUDVIG FETERSEN, of Boston,` in the countyof Suffolk and State of Massachusetts, have invented certain new anduseful Improvements in Feathering PaddleVheels, of which the followingis afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specication, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of my impro vement. Fig. 2 is a sectionalfront elevation of the same, taken through the line y y, Fig. 1. Fig. 3is a sectional side elevation ofthe same, taken through the line x x,Fig. '2.

The object of this invention is to promote efficiency in the operationof paddle-wheels- The invention consists in a paddle-wheel constructedwith a rigid outer wheel and a loose inner wheel provided with stops tolimit its movement, and with hinged paddles held to their work by theconnecting-rods of the` outer wheel, whereby the paddle-wheel will workwith equal efficiency in both directions, as will be hereinafter fullydescribed.

A represents the wheel-shaft, which is journaled to the boat andconnected with the driving-engine in the ordinary manner.

To the shaft A are rigidly attached the side frames, B, of the outerwheel, the rims of which are connected by rods C, as many rods C beingused as the wheel is to have paddles.

Upon the shaft A, at the inner side of the wheel-fran1es B, areplacedthe side frames, D, of the inner wheel, the rims of which areconnected by rods E, and which are kept at the proper distance apartupon the shaft A by collars F, connected by bars G, by a tubular washer,or by other suitable means. The inner wheel, D E, moves freely upon theshaft A; but its movement is limited by blocks H, attached to the rimsof the wheel-frames D, and which engage with the spokes oftheWheelframes B. Theinner Wheel, D, is made smaller than the outer wheel,B, and to the connectingrods E are hinged, by straps I or other suitablemeans, the inner edges of the paddles J, which project between theconnecting-rods C of the said outer wheel, B. With this construction,when power is applied to the shaft A, the paddles .I will be forcedthrough the water bythe pressure against them of the rods C, as shown inFigs. 1 and 3. With this construction, also, the wheel will work withequal efficiency in both directions, and should the engine be stopped,locking the shaft A and outer wheel, B C, the countencurrent in thewater will reverse the paddles and check the advance of the vessel.

The paddles J can be made of any desired shape and size. 1

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is*

1. Apaddle-wheel constructed substantially as herein shown anddescribed, and consisting of the rigid outer wheel, the loose innerwheel having stops H, and the hinged paddles J, as set forth.

2. In a paddle-wheel, the combination, with the shaft A, the rigid outerwheel, and the loose inner wheel, of the hinged paddles J and the stopsH, substantially as herein shown and described, whereby the paddle-wheelwill work with equal efficiency in both directions, as set forth.

3. In a paddle-wheel, the combination, with the side frames, D, of theloose wheel and the side frames, B, of the rigid wheel, of thestopblocks H, substantially as herein shown and described, whereby themovement of theloose wheel is limited, as set forth.
